Hybrid snakehead(Channa maculate♀×Channa argus♂)and Channa argus with the nearly same standard were selected to study contrastively for evaluating their flesh quality. Then, muscle nutrients composition, free amino acid content, physical parameters and flesh texture parameters were determined to analyze the flesh quality. About muscle nutrients composition , there were no differences(P＞0.05)in muscle crude protein , crude ash and crude fat between hybrid snakehead and Channa argus, but muscle moisture of hybrid snakehead was increased significantly ( P<0.01) .The contents of total free amino acids, flavor amino acids and essential amino acid of hybrid snakehead increased by 7.90%, 9.19% and 9.01%, respectively. About flesh physical index between hybrid snakehead and Channa argus, while the muscle fiber diameter and water loss rate of hybrid snakehead reduced significantly (P< 0.01), myofibril length of hybrid snakehead was increased significantly ( P< 0.01). Compared with the group of Channa argus, textural parameters of hybrid snakehead, including springiness, hardness and chewiness were decreased significantly (P<0.01), whereas cohesiveness of hybrid snakehead was increased significantly ( P< 0.01).However, there were no differences(P＞0.05)in resilience among hybrid snakehead and Channa argus. Therefore, it came to the conclusion that flesh quality of muscle nutrients composition and textural parameters were nearly accordant between hybrid snakehead and Channa argus, and that flesh quality of free amino acid content and physical indices of hybrid snakehead were better than Channa argus’s.
